Fallout: New Vegas originally had three races

Only one race (human) made it into Fallout: New Vegas as the player character's default background. But originally, Obsidian Entertainment wanted to add ghouls and super mutants as playable races.

In a feature article published by Eurogamer, Obsidian CEO Feargus Urquhart revealed that Obsidian was encouraged not to implement additional races by Bethesda during the game's development. Urquhart blamed the prohblem on the game's engine, citing complications with how it would process different races.

"It really had to do with how all the weapons and armor worked," he said to Eurogamer. "Trying to have them all work with ghouls and super mutants was just going to be—[Bethesda] felt like it was going to be a nightmare."

Bethesda didn't outright ban ghouls and super mutants as playable races. Rather, the publisher gave a strong suggestion against the idea, encouraging Obsidian to stick to a human-centric RPG experience. Thus, New Vegas as players know it today.

Several other interesting tidbits were revealed in Eurogamer's report. Obsidian knew early on that Fallout: New Vegas wasn't intended to be a fourth game. But Urquhart explained that Obsidian wanted to make sure the game was a full title, and not just a spin-off to tide over fans between Fallout 3 and Fallout 4.

"It was meant to be not the sequel," Urquhart said. "It was meant to be an offshoot project. But we were actually worried about that, about people thinking of it as just a big expansion."

So in turn, Obsidian turned to the West Coast, choosing Las Vegas and going all out with the idea.

"We put together a very short pitch, probably three pages," Urquhart said. "The first time we pitched it we pitched it as Fallout: Sin City. Very quickly it got changed to Fallout: Vegas and then became Fallout: New Vegas."

Fallout: New Vegas originally released for PC, PlayStation 3, and Xbox 360 in 2010. Bethesda's upcoming installment in the series, Fallout 4 VR, launches for HTC Vive later this year on Dec. 12.
